Snap-action limit switch for control-panel position feedback
The Omron SS-1GLT-4 is a limit switch from the Limit Switches class, used as a position- or travel-sensing element in control panels and machine guarding where a snap-action contact converts a mechanical actuator position into a discrete electrical signal.
Panel-side role and what drives the fit decision
Limit switches in this class land on machine doors, guard interlocks, and conveyor limit cams, where the actuator lever, plunger, or roller sweeps the internal contact through a snap-action transition and the output feeds a safety relay, contactor coil, or PLC discrete input. For an integrator, the deciding parameters on this family are the actuator style, the contact arrangement (SPDT/DPDT), the rated insulation voltage and current, and the mechanical endurance figure — these set whether the switch survives the machine's cycle count before reaching its electrical and mechanical life limits.
