摘要： A slit is formed in a plunger of a limit switch in such a manner that an amount of light incident on a light receiving element is changed in accordance with displacement of the plunger. The limit switch is provided with a setting processing unit (123) for setting a voltage value outputted from the light receiving element as a threshold value when a setting instruction is inputted in a state where the plunger is displaced to a designated position by a user, a position detecting unit (113) for performing detection processing of detecting whether or not the plunger is placed at a closer position to a reference position than to the designated position by comparing the set threshold value and the voltage value outputted from the light receiving element, and an output signal controlling unit (119) for outputting a signal based on a result of the detection processing. Thereby, the switch for outputting the signal in accordance with a position of a displacement member, the switch being capable of easily outputting the signal in accordance with a desired position of the displacement member without need for an adjusting screw can be provided.

摘要： A switch provided with an actuation body to be displaced due to contact with a physical body and operated in accordance with a position of the actuation body includes a mode switching unit (125) for switching a mode to any of a learning mode and a prediction mode, a position detecting unit (121) for detecting at least preliminarily fixed first and second positions of the actuation body (7), a time measuring unit (127) for measuring a time from when the first position is detected until when the second position is detected, a reference time setting unit (131) for setting a reference time based on the time measured in the learning mode, a comparing unit (133) for comparing the measured time and the reference time in the prediction mode, and a notifying unit (135) for notifying of an alarm in a case where the measured time is greater than the reference time in the prediction mode as a result of comparison. Thereby, the switch capable of being applied to a change in moving speed due to a change in a production line or the physical body or the like and reliably grasping slowing-down of the moving speed of the actuation body over a long time can be provided.

摘要： A push-button switch has a plunger to be pressed so as to activate its main body supported by a base member. A cap serving as a pressing member is on an outer edge portion of the plunger. The outer periphery of the cap is surrounded by a frame part of a lens member made of a transparent resin material such that the light from a light source disposed near the center of the plunger is guided to the upper edge part of the frame part.
