Voltage controlled switch, application method thereof and alarming system using voltage controlled switch

Abstract

The invention relates to a voltage controlled switch, which comprises a bistable resistive element. The bistable resistive element comprises a polymeric carrier and a plurality of metal particles dispersed in the polymeric carrier, and has a low-resistance working state and a high-resistance working state. When the bistable resistive element works in the low-resistance working state, conductive metal wires are formed on the surfaces of the plurality of metal particles, and the plurality of metal particles form a conductive path by the conductive metal wires. When the bistable resistive element works in the high-resistance working state, the conductive metal wires on the surfaces of the plurality of metal particles are broken to disconnect the conductive path. A low-resistance working state triggering signal is an excitation electric field. A high-resistance working state triggering signal is a dropout voltage signal. The invention also relates to an application method for the voltage controlled switch and an alarming system using the voltage controlled switch.

Description

technical field [0001] The invention relates to a voltage-controlled switch, a method for applying the voltage-controlled switch and an alarm system using the voltage-controlled switch. Background technique [0002] In some occasions that require anti-theft or shockproof, such as safes, testing machines, etc., a voltage-controlled switch is needed to monitor the change of the working pressure of the occasion. The voltage-controlled switch can not only sense the working pressure, but also keep the pressure-controlled switch at a fixed value according to the change of the working pressure when the change of the working pressure is greater than or less than a set value. working state, so that an alarm system connected with the pressure-controlled switch can remain in the alarm state, even if the change of the working pressure of said occasion is eliminated. [0003] In order to enable the voltage-controlled switch to maintain a fixed working state when pressure changes are mon...
