Therefore, the switch according to the present invention comprises a main body block having an operation input portion and a switch block having a terminal portion and a contact portion and connected to the rear end of the main body block. , It is detachably connected by engagement with a connecting hook that can be flexed outward by relative movement of the both in the front-rear direction. The switch block having a connecting portion with the operation input portion is movable in the front-rear connecting direction between the main body block and the switch block, and has a position that covers the outer surface of the engaging portion of the connecting hook and prevents the bending of the connecting hook. A switch block equipped with terminals to be connected is mounted on a panel, which is characterized in that an attachment / detachment operation section that is spring-biased toward Together it is obtained by can be detached from the body block that, perform the connection and release of the body block and the switch block easily, yet is obtained by so as not to come off unintentionally. The present invention will be described in detail below with reference to the illustrated embodiment. This switch has a main body block A having a push button 2 as an operation input section and a contact section (not shown) including a micro switch and the like. The main body block A is composed of a switch block B having a terminal 62 protruding from one end.
The main body 1 in FIG. 1 is provided with a male screw on its outer peripheral surface to which a nut 16 is screwed, and a plurality of elastic connecting hooks 15 project from the end of the main body 1 on the side opposite to the surface on which the push button 2 is arranged. It is set up. The main body block A is inserted into the mounting hole of the board from the front side, and is attached to the board by screwing the nut 16 into the main body 1 on the back side of the board. Reference numeral 17 in FIG. 2 is a square washer having claws provided at the four corners. On the other hand, the switch block B has a cylindrical case 3, a movable element 4 which is slidably disposed in the case 3, a part of which protrudes from one end of the case 3, and a terminal 62. The base 6 that closes the opening on the other end surface of the case 3
And a ring 5 slidably arranged on the outer periphery of the case 3, a plurality of grooves 30 are formed on the outer peripheral surface on one end side of the case 3, and each groove 30
A protrusion 31 is provided midway. As is apparent from FIG. 4, the ring 5 is biased toward one end side connected to the main body block A by a spring 50 arranged between one end of the inner surface of the ring 5 and the base 6. A pair of operating projections 51 is provided at the end on the terminal 62 side.
Is provided, and a protrusion 63 protruding from the base 6 is provided in an elongated hole 52 formed in the operating protrusion 51.
Is slidably engaged, so that the slidable range of the ring 5 is set. Then, when mounting and wiring the switch block B on the panel, the block block A and the switch block B are separated from each other, and the block block A is mounted on the panel as described above. Is also not connected to the main body block A. After that, the switch block B may be connected to the main body block A. As shown in FIGS. 5 (a), (b) and (c), this connection can be achieved by pressing the switch block B against the main body block A attached to the board so that the groove 30 of the case 3 can be removed. When the connecting hook 15 gets over the protrusion 31 located inside, the ring 5 is pushed by the connecting hook 15 and retracts relative to the case 3 to allow the connecting hook 15 to engage with the protrusion 31. If the connection hook 15 and the projection 31 are engaged with each other and the connection hook 15 is housed in the groove 30, the ring 5 is moved forward by the bias of the spring 50 to cover the tip end of the connection hook 15. Make sure that the connection by the connection hook 15 does not accidentally come off. When the main body block A and the switch block B are thus connected, the operation of pressing the push button 2 of the main body block A is transmitted to the contact portion in the switch block B through the mover 4 of the switch block B. To remove the switch block B from the main body block A, the ring 5 of the switch block B may be pinched and pulled backward. By this operation, first, the ring 5 is retracted to release the tip of the connecting hook 15, and by further pulling the ring 5, the connecting hook 15 bends and the protruding portion is released, as shown in FIG. 5 (d). Remove from 31. However, when the switch block B is pulled without the ring 5, since the ring 5 regulates the bending of the connecting hook 15, the switch block B does not have the body block A.
It does not come off. Since the operation part for attaching and detaching the switch block B from the main body block A is on the side of the switch block B, and the operation direction is the front-back direction which is the connecting and disconnecting direction of the switch block B to and from the main body block A, a plurality of operation parts Even if the individual switches are arranged side by side and attached to the board, the attachment / detachment of the switch block B is easy. In particular, in the switch here, the switch block B is removed by pulling the ring 5 and the switch block B is attached by pushing the base 6, but the ring 5 is used for operation as described above. Protrusion 5
1 is provided so that the operation of pinching and pulling the ring 5 can be easily performed, and also when pushing the base 6, a pair of operating projections 61 projecting from the base 6 to the outer surface of the ring 5 are projected. Then, by pinching and pushing these protrusions 61, the finger does not interfere with the movement of the ring 5 at the time of attachment. In addition, these operation projections 51, 6 which are operation parts for attachment / detachment
As shown in FIG. 3, when the push button 2 of the switch is square, as shown in FIG. 3, it is positioned on the diagonal line. The degree of obstruction is small, and in this respect also, the attachment / detachment operation of the switch block B is facilitated. Although the operating projection 61 serves as an operating portion when the switch block B is attached, it also functions as a member that receives a load when the ring 5 is pulled to remove the switch block B. Reference numeral 64 in FIG. 4 denotes a groove formed on the inner surface of the operating projection 61, on which the projection 53 protruding from the outer surface of the ring 5 is located.

[Effect of device]
