Abstract

The invention provides a waterproof limit switch for an elevator. The device comprises a body and a trigger ejector rod, the waterproof limit switch further comprises a waterproof shell and a waterproof cover. The body is arranged in an inner cavity of the waterproof shell. The waterproof cover is in a semispherical shape. The waterproof cover covers the triggering ejector rod and is connected with the waterproof shell; the contact parts of the waterproof cover and the waterproof shell are sealed, the waterproof cover is made of an elastic material; in the waterproof limit switch, the waterproof shell is arranged on the limit switch, and the waterproof cover is arranged on the trigger ejector rod, so that hidden dangers such as water seepage of the limit switch are avoided, and the stability of the limit switch is ensured.

Description

technical field [0001] The invention relates to the field of electrical equipment manufacturing, in particular to a waterproof limit switch for an elevator. Background technique [0002] The limit switch is a commonly used small current master electrical appliance. Use the collision of the moving parts of the production machinery to make the contact move to realize the connection or break of the control circuit to achieve a certain control purpose. [0003] In the control circuit of the elevator, the limit switch is used to control the switch of the car and the start and stop of the elevator. Once the water seeps inside the limit switch, the limit switch will fail, which may cause serious accidents. Contents of the invention [0004] The technical problem to be solved by the present invention is that the existing limit switch does not have a waterproof function. The present invention provides a waterproof limit switch for elevators to solve the above problem. [0005] Th...
