The invention discloses a limiting switch with a protective device, which includes a box, A limiting switch is fixedly installed at that bottom of the box body, the box body is provided with a cable hole at a position corresponding to the cable inlet on the limit switch, the box body is provided with a rotating shaft opening at a position corresponding to the rotating shaft on the limit switch, The rotating shaft of the limit switch is provided with a sliding block, one end of the sliding block is connected with a compression spring, the other end of the compression spring is connected with abaffle plate, the baffle plate is arranged at the bottom of the box body, one side of the baffle plate is the side of the box body, and the other side of the baffle plate is a partition plate, and twoopposing limit blocks are arranged between the baffle plate and the sliding block. The invention provides a limit switch with a protective device, which has stable performance and can effectively prevent damage phenomenon of internal components of the limit switch in the process of use.
Description
technical field [0001] The invention belongs to the technical field of limit switches, and in particular relates to a limit switch with a protective device. Background technique [0002] Limit switches, also known as travel switches, can be installed on relatively stationary objects (such as fixed frames, door frames, etc., referred to as still life) or moving objects (such as driving, doors, etc., referred to as animals). When the animal approaches the still object, the linkage of the switch actuates the contacts of the switch causing closed contacts to break or open contacts to close. The circuit and the motor are controlled by the change of the open and closed state of the switch contact. [0003] The limit switch is a commonly used small current master electrical appliance. It is a switch that is installed in a metal casing or a plastic casing to protect the small switch from external force, water, oil, dust, etc. In the electrical control system, the function of the l...
