Problems solved by technology

[0002] Current tools such as electric drills and chainsaws usually use push switches in order to consider safety and prevent the running tools from falling and causing harm to users. It will cause the user's hand fatigue and affect the work, and the normally open and normally closed switch cannot guarantee the safety of the operator when the tool falls. On the other hand, when the tool falls to the ground without being operated by anyone Potential safety hazard, lack of warning function for users

Abstract

The invention discloses a dual-mode electric switch with a fall protection reminding function; it includes a main box body, a fixed plate cavity is arranged in the main box body, a fixed plate is slidably connected to the fixed plate cavity, and the front end surface of the fixed plate is symmetrically fixed up and down. It is connected with a fixed contact, and the fixed contact is fixedly connected with wires extending outward to the outside world. The left and right sides of the fixed plate cavity are symmetrically connected with a sliding plate cavity. The magnetic push plate can be used in two modes: press power on and switch power on. To meet the working needs of different situations, at the same time, if the main box is accidentally dropped when it is in the switch power-on mode, the sliding contacts on the left, right, left, and right sides of the second compression spring will automatically disengage to complete the power-off. To prevent injury to the operator, when the main box falls to the ground, the bell will continue to sound to warn the user.

Description

technical field [0001] The invention relates to the technical field of electric switches, in particular to a dual-mode electric switch with a fall protection reminder function. Background technique [0002] Current tools such as electric drills and chainsaws usually use push switches in order to consider safety and prevent the running tools from falling and causing harm to users. It will cause the user's hand fatigue and affect the work, and the normally open and normally closed switch cannot guarantee the safety of the operator when the tool falls. On the other hand, when the tool falls to the ground without being operated by anyone It is a potential safety hazard and lacks the function of warning users. Contents of the invention [0003] In view of the deficiencies of the above-mentioned technologies, the present invention proposes a dual-mode electric switch with a fall protection reminder function, which can overcome the above-mentioned deficiencies. [0004] The pre...
