Compared with the prior art, the invention has obvious beneficial effects; the technical scheme shows that: a microswitch is installed at the lower end of a support, an angle piece is installed on the side face of the microswitch, a sleeve is inserted into the upper end of the support and is screwed into a nut for connection, a reset button is fixedly connected to the upper end of a connecting rod, a spring B is sleeved on the lower end of the connecting rod and is inserted into the sleeve, a gasket is sleeved on the upper end of a rack and is screwed into a button head, a spring A is sleeved on the middle of the rack and is inserted into the support, the lower end of the rack is inserted into the angle piece on the side face of the microswitch, a short spring plunger is installed in the middle of the rack, a rocker plate is placed behind the support, the two ends of the rocker plate are screwed into screws respectively for hinging, and the two ends of the spring B are hung on a cotter pin and the rocker plate respectively. The button head is pressed, a spring A at the lower end of the button head is compressed, the button head pushes a rack, the rack drives a short spring plunger to move downwards, the short spring plunger presses a microswitch, a hook-shaped part arranged at the front end of a rocking plate is clamped into a wavy tooth arranged on the rack and locked at a pressing position, and a response electric signal is output; when the reset button is pressed, a spring B below the reset button is compressed, the reset button drives a connecting rod to move downwards, the connecting rod pushes a boss arranged at the front end of a rocking plate, the rocking plate rotates on a support by taking a screw as a center, a hook-shaped part arranged at the front end of the rocking plate is separated from a wavy tooth arranged on a rack, the rack moves upwards, a short spring plunger is separated from a microswitch, and a button head is reset; the microswitch stops outputting the electric signal. The locking of the button head is realized by a wavy toothed groove on the rack and a hook-shaped groove arranged at the front end of the rocking plate. Because the short spring plunger has certain flexible volume, through the short spring plunger position on the regulation rack, can ensure that the switch during operation is in the overtravel scope, can guarantee the reliable output of corresponding signal of telecommunication. The device has the advantages of small volume, compact structure, convenient assembly and disassembly and high reliability.
