Abstract

The invention discloses an ON-OFF-ON bridge type switch with locking mechanisms, which is suitable for electric tool. The bridge type switch comprises a switch set and a bracket; the switch set is fixed to the bracket and is provided with a first key, a second key and a middle shaft; the switch also comprises a sliding mechanism capable of sliding along a direction parallel to the middle shaft and locking mechanisms of the first key and the second key; and when the sliding mechanism slides to the locking state, the locking mechanisms of the first key and the second key occupy space required by starting the first key and the second key respectively. Using the above technical scheme, the first key and the second key can be locked at the same time by making the sliding mechanism do sliding movement once, so that the space required by starting the first and second keys can be occupied at the same time, thereby greatly increasing bearing force in a switch locking state without start of the switch.

Description

technical field [0001] The invention relates to an ON-OFF-ON bridge switch, in particular to an ON-OFF-ON bridge switch with a locking mechanism, which is suitable for electric tools. Background technique [0002] The switch on the electric tool needs to be equipped with a switch locking mechanism in order to prevent the tool from starting when it is misoperated. The locking mechanism on the ON-OFF-ON bridge switch usually used on power tools has certain defects: in the locked state, if a relatively small force is applied to the switch, the switch can still be activated and is prone to failure; in addition, ON- The OFF-ON switch may have a problem of poor reset during use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ON-OFF-ON bridge switch with a locking mechanism that is easy to lock / unlock and can withstand a relatively large force in the locked state so that it is not easy to start. [0004] In order ...
