  At present, it has begun to consider using the above-described wireless signal as a switch for factory automation (FA) equipment. The wireless switch is required to transmit a switch signal to the base unit or the like reliably, and is desired to be as small and simple as possible in a usage environment such as a production line. For this reason, securing power necessary for communication has been a problem.

  Until now, the wireless switch has no means for confirming the reception status of the switch signal on the master unit side while realizing energy saving.

  Therefore, an object of the present invention is to provide a wireless switch that can reliably transmit a switch signal and grasp the reception state of the switch signal.

  The wireless switch of the present invention includes a button member, a power generation module, an RF module, and a notification unit. The button member is mounted on the housing in a movable state. The power generation module generates power using energy generated as the button member moves. The RF module is connected to the power generation module and transmits a switch signal using the power generated by the power generation module. The notification unit operates using the power generated by the power generation module. Then, the RF module controls the notification unit in one or more notification modes according to the strength or content of the reception confirmation signal corresponding to the transmitted switch signal.

  In this configuration, transmission of the switch signal, reception of the reception confirmation signal, and notification by the notification unit are realized by power generation by an operation on the button member that triggers the switch signal.

  According to the present invention, it is possible to reliably transmit the switch signal and grasp the reception state of the switch signal.

  The main body 72 has an outer shape with a predetermined size, and has, for example, a substantially rectangular parallelepiped shape as shown in FIG. A power generation module 80 is provided inside the main body 72. A hole 720 parallel to the first direction Dir1 is formed in the main body 72, and communicates with the accommodation space of the power generation module 80 and the outside on the surface 710 side.

  The power generation module 80 includes a power generation unit 801 and a power generation shaft 802. The power generation shaft 802 is partially inserted into a through hole formed in the power generation unit 801. The power generation unit 801 generates an electromotive force when the power generation shaft 802 moves in the through hole, that is, when the amount of insertion of the power generation shaft 802 into the through hole changes. More specifically, the power generation module 80 uses electromagnetic induction, and the power generation amount changes according to the moving speed of the power generation shaft 802, and the power generation amount increases as the moving speed increases (see FIG. 5). .

  The power generation module 80 is disposed in the housing 70 so that the power generation shaft 802 is parallel to the first direction Dir1 (a direction orthogonal to the surface 710 of the housing 70). One end of the power generation shaft 802 in the extending direction is inserted into the hole 720.

  Although not shown, the main unit 72 also incorporates each functional unit of a wireless switch, which will be described later with reference to FIG.

  The support portion 71 includes a fixing member 701 attached to the main body portion 72, and a first member 711 and a second member 712 that are disposed outward from the surface 710 of the housing 70.

  The first member 711 is a cylinder. The first member 711 has a thick portion and a thin portion along the axial direction of the cylinder, and the thick portion is disposed on the fixed member 701 side. The thick part and the thin part have the same inner diameter. That is, the outer diameter of the thick part is larger than the outer diameter of the thin part.

The second member 712 is connected to the fixing member 701 via a cylindrical connection portion 713. The inner diameter of the connecting portion 713 is substantially the same as the opening diameter of the second member 712.

  The internal space of the first member 711, the opening of the second member 712, the internal space of the connecting portion 713, and the opening of the fixing member 701 are in communication. The opening of the fixing member 701 communicates with the hole 720 of the main body 72.

  The protrusion 73 has a substantially rectangular parallelepiped shape, is connected to the side surface of the second member 712 on the center opening side, and projects from the side surface to the center opening. The protrusion 73 is fixed to the second member 712. For example, the protrusion 73 is integrally formed with the second member 712, and the protrusion 73 is integrally formed with the support 71.

  The cover member 20 is a cylinder. The cover member 20 is disposed on the outer surface side of the first member 711 in the support portion 71. The inner side surface of the cover member 20 is in contact with the outer side surface of the thick part of the first member 711. As a result, a circular groove is formed between the inner surface of the cover member 20 and the outer surface of the thin portion of the first member 711 in plan view.

  The button member 30 includes a surface member 301, a central member 302, and a side member 303. The surface member 301 is a disk, the central member 302 is a column, and the side member 303 is a cylinder. The diameter of the central member 302 is smaller than the diameter of the surface member 301. The outer diameter of the side member 303 is the same as the diameter of the surface member 301, and the inner diameter of the side member 303 is larger than the diameter of the central member 302. The central member 302 and the side member 303 are in contact with the back surface of the front surface member 301. The central member 302 is disposed at the center of the surface member 301 in plan view. The side member 303 has a shape along an outline (periphery) of the surface member 301 in plan view. With this shape, a cylindrical space having a predetermined thickness sandwiched between the central member 302 and the side member 303 is formed on the back surface side of the front surface member 301. The side member 303 is inserted into a groove formed by the cover member 20 and the thin portion of the first member 711. Since the groove has a deep shape in the first direction Dir1, the button member 30 moves along the first direction Dir1 when the surface member 301 is pushed in from the surface side.

  The first plunger 41 is disposed in a cylindrical space sandwiched between the button member 30, the first member 711, and the second member 712. The 1st plunger 41 is a substantially cylinder, and has a thick part and a thin part along the axial direction of a cylinder. The axial direction of the first plunger 41 is parallel to the first direction Dir1.

  The thick part is disposed on the button member 30 side, and the thin part is disposed on the housing 70 side (second member 712 side). The inner diameter of the thick part and the inner diameter of the thin part are the same, and the outer diameter of the thick part is larger than the outer diameter of the thin part.

  The surface of the thick part on the button member 30 side is in contact with the back surface of the front surface member 301 of the button member 30. The outer surface of the thick part is in contact with the inner surface of the first member 711.

  The first plunger 41 includes a cam projection 411 that projects inward (center side of the cylinder) at a predetermined position in the axial direction.

  The second plunger 42 is disposed across the cylindrical space surrounded by the button member 30, the first member 711, and the second member 712, the opening of the second member 712, and the internal space of the connection portion 731. ing. The 2nd plunger 42 is a substantially cylinder, and has a thick part and a thin part along the axial direction of a cylinder. The axial direction of the second plunger 42 is parallel to the first direction Dir1.

  The thin part is disposed on the button member 30 side, and the thick part is disposed on the housing 70 side (second member 712 side). The inner diameter of the thick part and the inner diameter of the thin part are the same, and the outer diameter of the thick part is larger than the outer diameter of the thin part.

  The thick portion is disposed across the cylindrical space surrounded by the button member 30, the first member 711, and the second member 712, the opening of the second member 712, and the internal space of the connection portion 731.

As shown in FIGS. 3 and 4, a groove 420 is formed in a region overlapping the second member 712 in the first direction Dir1 in the thick portion. The groove 420 has a shape that is recessed from the outer surface of the thick portion and extends along the circumferential direction. The width (length in the direction orthogonal to the circumferential direction) and depth of the groove 420 are set to dimensions that can be accommodated by the protrusion 73 of the housing 70.

  Furthermore, as shown in FIGS. 3 and 4, a concave portion 421 is formed in the thick portion. The recess 421 communicates with the groove 420 and is formed at a predetermined position in the circumferential direction. The recess 421 is formed in a size that can accommodate the protrusion 73.

  The portion of the thin portion opposite to the side connected to the thick portion is disposed between the central member 302 of the button member 30 and the first plunger 41. The outer surface of the portion disposed between the central member 302 and the first plunger 41 in the thin portion is in contact with the inner surface of the first plunger 41. A cam groove 412 is formed in the thin portion. The cam groove 412 penetrates through the thin portion and is formed at a predetermined angle such as 45 ° that is not parallel or perpendicular to the axial direction. The cam protrusion 411 of the first plunger 41 is inserted into the cam groove 412. With this configuration, the cam 400 that converts the movement of the first plunger 41 along the first direction Dir1 into the movement of the second plunger 42 in the circumferential direction is configured.

  The trigger spring 51 has a spiral shape. The trigger spring 51 is disposed in a cylindrical space surrounded by the first plunger 41, the second plunger 42, the first member 711, and the second member 712. The central axis of the spiral trigger spring 51 is parallel to the first direction Dir1. One end of the trigger spring 51 is fixed to the first plunger 41, and the other end is in contact with the surface of the step which is the boundary between the thick part and the thin part of the second plunger 42.

  The return spring 52 has a spiral shape. The return spring 52 is disposed in a cylindrical space surrounded by the first plunger 41, the second plunger 42, the first member 711, and the second member 712. The central axis of the helical return spring 52 is parallel to the first direction Dir1. One end of the return spring 52 is fixed to the first plunger 41, and the other end is disposed inside a trigger spring groove formed in the second member 712 and is in contact with the groove.

  The shaft 61 includes a bottom portion and a shaft portion, the bottom portion is a disc, and the shaft portion is a cylinder. The bottom is fixed to the end surface of the second plunger 42 opposite to the first plunger 41 side, that is, the housing 70 side (power generation module 80 side). The shaft portion protrudes from the end surface of the second plunger 42 on the housing 70 side to the housing 70 side, and the extending direction of the shaft portion is parallel to the first direction Dir1. A part of the shaft portion in the extending direction is inserted into the hole 720 of the main body portion 72. The tip of the shaft portion is in contact with the end portion of the power generation shaft 802.

  The wireless switch 10 having such a configuration generates power by the operations shown in FIGS.

(Power generation during button operation)
With reference to FIG. 3 (A)-FIG. 3 (F), the electric power generation operation | movement at the time of button operation is demonstrated.

  As shown in FIGS. 3 (A) and 3 (B), when an operator (for example, finger FG in FIG. 3 (A)) pushes the button member 30, according to the pushing amount, the button member 30 is It moves toward the housing 70 side along the first direction Dir1. At this time, the protrusion 73 of the housing 70 is disposed at a location not communicating with the recess 421 in the groove 420 of the second plunger 42. Therefore, even if the button member 30 moves along the first direction Dir1, the second plunger 42 does not move along the first direction Dir1. Therefore, the shaft 61 does not move along the first direction Dir1 and does not push the power generation shaft 802.

  When the button member 30 moves along the first direction Dir1 and the second plunger 42 does not move, the distance between the button member 30 and the second plunger 42 in the first direction Dir1 is shortened. Since the first plunger 41 is in contact with the button member 30, the first plunger 41 also moves along the first direction Dir1 as the button member 30 moves. Therefore, the distance between the first plunger 41 and the second plunger 42 in the first direction Dir1 is shortened.

  At this time, since the cam 400 is provided as described above, the second plunger 42 rotates about the first direction Dir1 as the rotation axis by the movement of the first plunger 41 along the first direction Dir1. Thereby, the protrusion 73 moves in the circumferential direction in the groove 420.

  Further, the first plunger 41 moves along the first direction Dir1 and the distance between the first plunger 41 and the second plunger 42 is shortened, whereby compressive stress is accumulated in the trigger spring 51. At this time, since the distance between the first plunger 41 and the second member 712 is also shortened, the stress is also accumulated in the return spring 52.

  Next, as shown in FIGS. 3 (C) and 3 (D), when an operator (for example, finger FG in FIG. 3 (C)) further pushes the button member 30, the button is pressed according to the push amount. The member 30 further moves toward the housing 70 side along the first direction Dir1. At this time, the protrusion 73 of the housing 70 partially enters the portion of the groove 420 of the second plunger 42 that communicates with the recess 421, but the protrusion 73 is not yet accommodated in the recess 421. Therefore, even if the button member 30 moves along the first direction Dir1, the second plunger 42 does not move along the first direction Dir1. Therefore, the shaft 61 does not move along the first direction Dir1 and does not push the power generation shaft 802.

  Further, the second plunger 42 further rotates with the first direction Dir1 as the rotation axis. Thereby, the protrusion 73 further moves in the circumferential direction in the groove 420. Further, as the distance between the first plunger 41 and the second plunger 42 is further shortened, a compressive stress is further accumulated in the trigger spring 51. At this time, since the distance between the first plunger 41 and the second member 712 is further shortened, stress is further accumulated in the return spring 52.

  Next, as shown in FIGS. 3E and 3F, when the operator (for example, the finger FG in FIG. 3E) further presses the button member 30, the button is pressed according to the pressing amount. The member 30 further moves toward the housing 70 side along the first direction Dir1. By this movement, the second plunger 42 further rotates, and the protrusion 73 overlaps with a portion communicating with the recess 421 in the groove 420. Thereby, the protrusion 73 does not contact the wall surface of the groove 420 on the first plunger 41 side.

  As described above, the trigger spring 51 is subjected to compressive stress. Therefore, when the protrusion 73 is separated from the wall surface on the first plunger 41 side in the groove 420, the stress of the trigger spring 51 is released.

  Since the button member 30 is pushed by the operator, the force due to the extension of the trigger spring 51 due to the release of the stress acts on the movement of the second plunger 42. Thereby, the 2nd plunger 42 moves to the housing | casing 70 side. With the movement of the second plunger 42, the shaft 61 moves in the direction of the power generation shaft 802 and pushes in the power generation shaft 802. Thereby, the power generation module 80 generates power.

  Here, the movement of the power generation shaft 802 is caused by the force caused by the extension of the trigger spring 51, and the extension of the trigger spring 51 occurs instantaneously when the protrusion 73 is accommodated in the recess 421. Therefore, the moving speed of the power generation shaft 802 is constant regardless of the speed at which the operator pushes it. Thereby, the power generation module 80 can obtain a stable power generation amount.

  Furthermore, since the movement of the second plunger 42 is urged by the trigger spring 51, and the release of the stress of the trigger spring 51 that causes this urging is instantaneous, the moving speed of the power generation shaft 802 is fast. Thereby, the electric power generation amount of the electric power generation module 80 can be enlarged.

  FIG. 5A is a graph showing the relationship between the pushing speed and the moving speed of the power generation shaft in the configuration of the present invention, and FIG. 5B shows the pushing speed and the moving speed of the power generating shaft in the comparative configuration. It is a graph which shows the relationship. The comparative configuration is a configuration that does not use a trigger spring, and the moving speed of the power generation shaft changes according to the pressing speed of the button member.

  As shown in FIG. 5B, in the comparative example, when the push speed of the button member changes, the moving speed of the power generation shaft also changes. That is, the amount of power generation also changes according to the pressing speed of the button member.

  However, as shown in FIG. 5A, in the configuration of the present invention, even if the push speed of the button member changes, the moving speed of the power generation shaft does not change, and the power generation amount is stabilized. Furthermore, since the moving speed of the power generation shaft is increased by the biasing by the trigger spring 51, the power generation amount is increased.

  As described above, by using the configuration of the present embodiment, a large amount of power generation can be stably obtained by pressing with a predetermined pressing amount regardless of the pressing speed.

(Power generation when the button returns)
With reference to FIG. 4 (A)-FIG. 4 (F), the power generation operation at the time of button return will be described.

  As shown in FIGS. 4A and 4B, while the operator (for example, the finger FG in FIG. 4A) is pressing the button member 30, the protrusion 73 is accommodated in the recess 421. Maintained.

  Next, as shown in FIGS. 4C and 4D, when the operator stops pushing the button member 30, the stress applied to the return spring 52 is released, and the button member 30, the first The plunger 41 and the second plunger 42 move in a direction away from the housing 70 (second direction Dir2 which is opposite to the first direction Dir1). As a result, the protrusion 73 moves from the recess 421 into the groove 420.

  At this time, along with the movement of the second plunger 42, the shaft 61 also moves in the second direction Dir2, and the power generation shaft 802 also moves. Therefore, the power generation module 80 can generate power even when returning. And since there is urging | biasing by the return spring 52, the electric power generation amount at the time of a return can also be improved.

  Next, as shown in FIGS. 4E and 4F, the button member 30, the first plunger 41, and the second plunger 42 are moved along the second direction Dir2 by the stress of the return spring 52. Move further. At this time, since the above-described cam 400 is provided, the second plunger 42 rotates in the direction opposite to that during the pushing operation. Thereby, it returns to a steady state.

  Thus, by using the configuration of the present embodiment, it is possible to generate power both when the button member 30 is pushed in and when the button member 30 is returned.

  The wireless switch 10 having such a power generation mechanism has the circuit configuration of FIG. FIG. 6 is a circuit diagram of the wireless switch according to the embodiment of the present invention.

  The wireless switch 10 includes a power generation module 80, a rectification unit 81, a power storage unit 82, a notification unit 83, an RF module 84, and an antenna 85.

  The power generation module 80 is realized by the above-described mechanism. The power generation module 80 is connected to the power storage unit 82, the notification unit 83, and the RF module 84 via the rectification unit 81.

  The rectifying unit 81 is configured by a rectifying element such as a diode connected to a signal line opposite to the ground line, for example. The rectifier 81 rectifies the power (voltage, current) generated by the power generation module 80. Note that the rectifying unit 81 may be configured by a diode bridge circuit such as a half-wave rectifier circuit or a full-wave rectifier circuit.

  The power storage unit 82 includes a capacitor 821. The power storage unit 82 stores the power rectified by the rectification unit 81.

  The RF module 84 is energized by the power generation of the power generation module 80 and uses this energization as a trigger to transmit a switch signal to the outside via the antenna 85. Here, the switch signal is a signal indicating that the button member 30 has been pushed. This can be used, for example, as a push button switch signal in an FA (factory automation) system.

  As described above, the wireless switch 10 according to the present embodiment can transmit a switch signal using the power generated by the pushing operation of the switch without using a primary battery or a secondary battery. At this time, as described above, since the wireless switch 10 can stably obtain a large amount of power generation, the power for transmitting the switch signal can be reliably ensured. Accordingly, the wireless switch 10 can reliably transmit the switch signal.

  Furthermore, the wireless switch 10 includes the following configuration in the notification unit 83.

  The notification unit 83 includes a light emitting module 830 and switch elements 834, 835, and 836. The light emitting module 830 includes a plurality of light emitting elements 831, 832, and 833. The light emitting elements 831, 832, and 833 have different light emission modes. For example, the light emitting elements 831, 832, and 833 are light emitting diodes having different emission colors. The switch elements 834, 835, and 836 are, for example, transistors. In the notification unit 83, lighting of the light emitting elements 831, 832, and 833 is controlled by a control signal from the RF module 84 to the switch elements 834, 835, and 836. For example, when an ON control signal is input to the switch element 834, the switch element 834 is turned on and the light emitting element 831 is lit. Similarly, when an ON control signal is input to the switch element 835, the switch element 835 is turned on, the light emitting element 832 is turned on, and when an ON control signal is input to the switch element 836, the switch element 836 is turned on. Thus, the light emitting element 833 is turned on. Light emitted from the light emitting elements 831, 832, and 833 is propagated to the outside through the light transmitting portion 74 (see FIG. 1) of the housing 70. Thereby, the operator can confirm light emission. At this time, the drive voltage to the light emitting elements 831, 832, and 833 is supplied from the power storage unit 82.

  With such a configuration, the wireless switch 10 can realize the following operation. 7A and 7B are diagrams showing a schematic configuration of a switch signal transmission system using the wireless switch of the present invention. FIG. 7A illustrates a system including a wireless switch and a parent device, and FIG. 7B illustrates a system including a wireless switch, a relay device, and the parent device.

  The system shown in FIG. 7A includes a wireless switch 10 and a parent device 91. The wireless switch 10 has the above-described mechanism and circuit configuration. Base unit 91 includes a main body 911 and an antenna 912. The main body 911 is connected to a network such as an FA system via a communication cable 900 such as a LAN cable.

  The wireless switch 10 transmits a switch signal Ssw when the push-in operation by the operator is accepted. The antenna 912 of the parent device 91 receives the switch signal Ssw, and the main body 911 of the parent device 91 sends a signal indicating reception of the switch signal Ssw via a communication cable 900 to a predetermined device (for example, PLC (Programmable Logic) in the network. Controller)).

  Further, the main body 911 generates a reception confirmation signal Srv and transmits it via the antenna 912. At this time, the main body 911 sets reception state data in the reception confirmation signal Srv. The reception state data is set based on the signal strength Issw of the switch signal Ssw when the base unit 91 receives the signal, and the signal strength Issw is greater than or equal to the strength threshold and the signal strength Issw is less than the strength threshold. The contents are set differently depending on the case. For example, if the signal strength Issw is greater than or equal to the strength threshold, the bit of the reception status data is set to “0”, and if the signal strength Issw is less than the strength threshold, the bit of the reception status data is set to “1”. . The signal strength Issw is detected by the main body 911 when the switch signal Ssw is received.

  The wireless switch 10 receives the reception confirmation signal Srv. The wireless switch 10 performs control of the notification unit 83 according to whether or not the signal strength Isrv of the reception confirmation signal Srv is equal to or higher than the strength threshold and the content (bit) of the reception state data. Specifically, the RF module 84 of the wireless switch 10 determines whether or not the signal strength Isrv of the reception confirmation signal Srv is equal to or higher than the strength threshold and the content (bit) of the reception state data, Either 832 or 833 is selectively lit.

  More specifically, the wireless switch 10 performs the following process. If the signal strength Isrv of the reception confirmation signal Srv is equal to or higher than the strength threshold and the bit of the reception confirmation data is “0”, the RF module 84 turns on the light emitting element 831 and does not turn on the light emitting elements 832 and 833. . If the signal strength Isrv of the reception confirmation signal Srv is less than the intensity threshold value or the bit of the reception confirmation data is “1”, the RF module 84 turns on the light emitting element 832 and turns on the light emitting elements 831 and 833. I won't let you. Further, the RF module 84 measures time from the time of transmission of the switch signal Ssw, and if the reception confirmation signal Srv cannot be received within a predetermined time from the start of time measurement (at the time of transmission of the switch signal Ssw), the light emitting element 833 is set. The light emitting elements 831 and 832 are not turned on.

  By executing such processing, the operator can surely recognize whether or not the switch signal Ssw is received by the parent device 91. Furthermore, the operator can recognize whether the wireless signal strength is equal to or higher than a predetermined signal strength, that is, the reliability of the wireless communication.

  At this time, by providing the power generation module 80 and the power storage unit 82 described above, the wireless switch 10 can receive the reception confirmation signal Srv without using a primary battery or a secondary battery, and can realize control of the notification unit 83.

  The processing of the wireless switch 10 including the processing of the RF module 84 can be realized by the flow shown in FIG. FIG. 8 is a flowchart showing processing of the wireless switch according to the embodiment of the present invention.

  With the above-described configuration, the wireless switch 10 stores power by storing a switch (pushing operation of the button member 30) (S11).

  The RF module 84 of the wireless switch 10 is activated by this power generation (S12). The RF module 84 transmits the switch signal Ssw using the activation as a trigger (S13). The RF module 84 starts timing from the time when the switch signal Ssw is transmitted (S14).

  If the time measured has reached the timeout time (S15: YES), the RF module 84 causes the light emitting element 833 to emit light and execute the third color light emission (S21). If the time measured has not reached the timeout time (S15: NO), the RF module 84 enters a reception standby state for the reception confirmation signal Srv. If the RF module 84 has not received the reception confirmation signal Srv (S16: NO), the RF module 84 continues timing.

  When receiving the reception confirmation signal Srv (S16: YES), the RF module 84 detects the signal intensity Isrv. If the signal intensity Isrv is less than the intensity threshold (S17: NO), the RF module 84 causes the light emitting element 832 to emit light and execute second color light emission (S20). If the signal strength Isrv is equal to or greater than the strength threshold (S17: YES), the RF module 84 demodulates the reception confirmation data.

  If the reception confirmation data is normal (if the bit of the reception confirmation data is “0”), the RF module 84 causes the light emitting element 831 to emit light and performs the first color light emission (S19). If the reception confirmation data is not normal (if the bit of the reception confirmation data is “1”), the RF module 84 causes the light emitting element 832 to emit light and performs the second color light emission (S20).

  Note that the above-described processing can also be realized in an aspect including a repeater 92 as shown in FIG. The system illustrated in FIG. 7B includes a wireless switch 10, a parent device 91, and a relay device 92. The repeater 92 includes a main body 921 and an antenna 922.

  The wireless switch 10 transmits a switch signal Ssw when the push-in operation by the operator is accepted. The antenna 922 of the repeater 92 receives the switch signal Ssw, and the main body 921 detects the received signal strength Issw. The main body 921 generates reception state data based on the signal strength Issw in the same manner as the parent device 91 described above. The main body 921 generates a relay switch signal Ssw1 including the reception state data and transmits it from the antenna 922.

  The antenna 912 of the parent device 91 receives the relay switch signal Ssw1, and the main body 911 detects the received signal strength Issw1. The main body 911 updates the reception state data on the basis of the signal strength Issw1 according to the same principle as that of the parent device 91 described above. The main body 911 generates a reception confirmation signal Srv including the reception state data and transmits it from the antenna 912. The updated reception status data is used for the reception confirmation signal Srv.

  The antenna 922 of the repeater 92 receives the reception confirmation signal Srv, and the main body 921 detects the received signal strength Isrv. Based on the signal strength Isrv, the main body 921 updates the reception state data based on the same principle as that of the parent device 91 described above. The main body 921 generates a relay reception confirmation signal Srv1 including the updated reception state data, and transmits it from the antenna 922.

  The wireless switch 10 receives the relay reception confirmation signal Srv1. The radio switch 10 executes the control of the notification unit 83 as described above according to whether or not the signal strength Isrv1 of the relay reception confirmation signal Srv1 is equal to or higher than the strength threshold and the content (bit) of the reception state data. .

  By executing such processing, the operator can surely recognize whether or not the switch signal Ssw has been received by the parent device 91 even when wirelessly via the relay device 92. Furthermore, the operator can recognize whether the wireless signal strength is equal to or higher than a predetermined signal strength, that is, the reliability of the wireless communication.

  In the above description, the power generation shaft is moved at a constant speed that is not affected by the pushing speed by the movement of the projection 73 with respect to the groove 420 and the recess 421 of the second plunger 42 and the operation and biasing of the trigger spring 51. showed that. However, a mechanism that does not move the shaft 61 (the power generation shaft 802) to a predetermined push amount (for example, a mechanism that temporarily stops movement due to the relationship between the structure and the structure), and a predetermined push amount. A structure in which a mechanism (for example, a mechanism using air pressure) that generates a predetermined bias when it reaches and moves the shaft 61 (power generation shaft 802) is disposed between the button member and the power generation module as an intermediate member. By using it, it is possible to realize the power generation mechanism described above.

  In the above description, the configuration including the return spring 52 is shown, but the trigger spring 51 may be included as a minimum configuration. However, the provision of the return spring 52 improves the power generation efficiency and is effective.

  In the above description, the light emission color of the light emitting element is shown differently, but the light emission pattern may be changed. In this case, at least one light emitting element is sufficient.

  Moreover, although the aspect which uses a light emitting element as a notification part was shown, the other aspect which can notify to an operator can also be used. For example, a sound generating element such as a buzzer can be used as the notification unit. A plurality of types of notification modes may be used. For example, sound and light may be used. However, a light-emitting element using a light-emitting diode has low power consumption and can emit light with small power, and thus is more effective for the configuration of this embodiment.

Moreover, although the aspect which utilizes the generated electric power for transmission / reception of a switch signal was shown in the above-mentioned description, it is also possible to use it for other signal processing. For example, the power generation unit having the above-described mechanism is used, and the power generated by the power generation unit can be used to transmit signals including various stored information.
