The MTL306D is a 3PDT miniature locking toggle switch designed for applications requiring secure position retention. It features a long bat actuator with chrome-plated copper alloy construction and operates over a temperature range of -20°C to +80°C. The switch has a contact rating of 6 A at 125 VAC and 3 A at 250 VAC, with an initial contact resistance of 20 milliohms maximum and break-before-make contact timing. The actuator travel is 24° with an actuation force of 0.5–1.5 kg, and the switch provides mechanical life expectancy of 100,000 cycles in the 3-position configuration. This switch is ideal for control panels, industrial equipment, and applications where reliable switching and position locking are essential.
