This is a TE Connectivity PCB-mount toggle switch from their standard industrial switching line, designed for through-hole installation in control panels and equipment requiring sealed operation. The On-Off-(On) momentary configuration with SPDT contacts supports 400 mA at 20 V dc. Critical verification: confirm IP67 sealing is maintained post-soldering and validate contact resistance degradation under thermal cycling within the -30 to +85°C operating window.
