Tongue-operated safety switches
By Alison Dunn
AutomationDirect has expanded its line of safety products with additional tongue interlock and cable-pull safety switches. Tongue-operated safety interlock switches are designed to fit to the leading edge of sliding, hinged or lift-off machine guards and provide positively operated switching contacts. They provide a tamper resistant actuator mechanism and robust position interlock detection for moving guards. Available in 22mm, 30mm and 40mm mounting profiles, models are available in plastic, aluminum and stainless steel housing options. The switches are designed with multiple actuator entry points and offer adjustable heads with 90-degree and 180-degree options; switch styles provide single and multiple half-inch female NPT conduit openings.
