Abstract
Disclosed in the utility model is a stroke control switch that comprises a pedestal, an upper cover and a movable piece. A connection point is arranged at one end of the movable piece; contacts are respectively arranged at two sides of the connection point of the movable piece on the pedestal, wherein one contact at one side is extended out of the pedestal to form a normally closed terminal and the other contact at the other side is extended out of the pedestal to form a normally open terminal. Especially, the stroke control switch is provided with a switching resetting unit formed by the movable piece, a piston type button, a reset spring sheet, and a support. Based on the support, the connection point of the movable piece is communicated with the normally open terminal under the effect of dominance of the piston type button and the connection point of the movable piece is communicated with the normally closed terminal under the effect of dominance of the reset spring sheet. According to the utility model, the beneficial effects of the stroke control switch are as follows: the switch is provided with the switching resetting unit; the connection point of the movable piece enables the switch to be in a normally open or normally closed state under the effect of dominance of the reset spring sheet; and with utilization of the switching resetting unit, the switch can be opened or closed according to the using condition.
Description
Technical field
The utility model relates to a kind of switch, relates in particular to a kind of travel control switch, belongs to technical field of electronic components.
Background technology
The switch that generally needs the equipment of Stroke Control to be provided with is the conventional push button switch, short time action need toggle switch button carries out Stroke Control, processing ease causes the problems such as the short circuit of opening circuit so that the switch parts are impaired like this, and control stroke accuracy is inadequate; The partial journey control switch is also arranged on the market, the inside of these travel control switchs arranges more loaded down with trivial details, and the reseting shrapnel lever-type structure all is not set.
Summary of the invention
The purpose of this utility model is to propose a kind of travel control switch, solves the loaded down with trivial details problem of travel switch internal structure.
The purpose of this utility model, to be achieved by the following technical programs: a kind of travel control switch, but comprise base, loam cake and moving plate, but an end of described moving plate is provided with contact, but described base is respectively equipped with a contact in the contact both sides of moving plate, and a side contact is extended base and is formed normally closed terminal, the opposite side contact is extended base and is formed Chang Kaiduan, it is characterized in that: but described travel control switch is provided with by moving plate, piston type button, reseting shrapnel and a switch back unit that is configured to; Be connected with Chang Kaiduan but account under the leading effect at the piston type button based on the contact of the described moving plate of support, but and the contact of described moving plate account under the leading effect at reseting shrapnel and be connected with normally closed terminal.
Further, but two contacts of the contact of described moving plate and base are anti-breakdown current reaches the above silver contact of 12A.
The beneficial effects of the utility model are mainly reflected in: switch is provided with the switch back unit, but the contact of moving plate accounts at reseting shrapnel and makes switch be in normally closed or normally open under the leading effect, by the switch back unit, can be according to behaviour in service closure or openness switch.
Description of drawings
Fig. 1 is an example structure schematic diagram of the utility model travel control switch.
Fig. 2 is another example structure schematic diagram of the utility model travel control switch.
Embodiment
Following constipation closes the embodiment accompanying drawing, embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
The structure of the utility model travel control switch, such as Fig. 1 or shown in Figure 2, but base 1, loam cake 2 and moving plate 3, but an end of moving plate 3 is provided with contact 31, but base 1 is respectively equipped with a contact in contact 31 both sides of moving plate 3, and a side contact 4 is extended base and is formed normally closed terminal 41, opposite side contact 5 is extended base and is formed Chang Kaiduan 51, Chang Kaiduan is the two poles of the earth of circuit with support, it is characterized in that: but travel control switch is provided with the switch back unit that is made of moving plate 3, piston type button 6, reseting shrapnel 7 and support 8; But non-contact end and the support of moving plate connect as one, reseting shrapnel one end is connected in support, it is relative with piston type button butt direction that but the other end acts on the moving plate bottom, be connected with Chang Kaiduan 51 but account under the leading effect at the piston type button based on the contact of support moving plate, but and the contact 31 of described moving plate 3 account under the leading effect at reseting shrapnel 7 and be connected with normally closed terminal 41.
But the contact 31 of this moving plate 3 and two contacts of base 1 are anti-breakdown current reaches the above silver contact of 12A.
Embodiment oneAs shown in Figure 1, a kind of travel control switch is pressed piston type button 6, but pressure-acting is in moving plate 3 middle-ends, but moving plate 3 is made seesaw type tectonic movement take support 8 as fulcrum, pressed home shell fragment 7, so that elastic deformation occurs back-moving spring 7, but the contact 31 of moving plate 3 contacts at the contact 51 of Chang Kaiduan 5, but support 8 moving plates 3 and normal beginning 5 produce the loop, and switch switches to an other utmost point at this moment; When the piston type buttons force finishes, but the force reaction that reseting shrapnel 7 elastic deformations produce in moving plate 3 so that piston type button 6 resets, but contact 41 butts of moving plate 3 contacts 31 and normally closed terminal 4, switching over resets.
Embodiment twoAs shown in Figure 2, a kind of travel control switch, but moving plate engages with an end of support 81 and is integrated, the other end of support 81 is connected to support 82 and take support 82 as fulcrum, piston type button 6 is pressed, but pressure-acting is in moving plate 3 and support 81 fastening ends, support 81 is under pressure and does the lever motion take support 82 as fulcrum, but when moving plate 3 moves downward reseting shrapnel 7 is strained, but when reseting shrapnel 7 elastic deformations reach certain displacement, forced moving plate 3 to move downward, but so that the contact 31 of moving plate 3 contacts at the contact 51 of Chang Kaiduan 5, support 8, but moving plate 3 and normal beginning 5 produce the loop, and switch switches to an other utmost point at this moment; When piston type button 6 application of forces finished, elastic deformations occured in reseting shrapnel 7, so that piston type button 6 resets, but contact 41 butts of moving plate 3 contacts 31 and normally closed terminal 4, switching over resets.
Can find out by above-mentioned character express, after the utility model travel control switch drops into and implements, its beneficial effect is mainly reflected in: switch is provided with the switch back unit, but the contact of moving plate accounts at reseting shrapnel and makes switch be in normally closed or normally open under the leading effect, by the switch back unit, can be according to behaviour in service closure or openness switch.
In addition to the implementation, the utility model can also have other execution mode.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
