Fingertech Switch

Has your robot been lacking a high-current power switch?  Tired of plugging and unplugging the battery during an intense competition? - Our Mini Switch can be activated with the simple twist of an allen key. - No other switch is as small, lightweight and powerful! - Read Servo Magazine's keen review of the Mini Power Switch here: Servo 2013-04 Mini Switch Review.pdf Specifications: Material: High-temperature nylon, copper terminals, aluminum screw Dimensions: 12.7 x 12.7 x 6.35mm (0.5 x 0.5 x 0.25in) Copper terminals: 3.5mm x 1mm (0.138 x 0.04in) extend 6.35mm (0.25in) from switch body Weight: 2.15grams (0.076oz) Installation: Two mounting holes, spaced 7.62mm (0.3in) apart, can pass-through 2mm or 2-56 screws, or can be tapped for 3mm or 4-40 screw threads. Tip: Connect the battery to the terminal closest to the screw head. The screw head is part of the circuit (constant connection to the far terminal), so this will ensure it is not live when the robot is off. Allowable soldering temperatures: 350C : continuous 400C : 1min 450C : 12s 480C : 8s Operation: To connect the two copper terminals, use a 3/32" hex wrench to tighten the screw (clockwise). * It does not take a lot of force to make a good connection - just finger-tight. (The nylon is undersized to keep the screw from backing out due to vibrations.) One full rotation counterclockwise disconnects power. Current Ratings (using 16-gauge wire): Rated Current: 40A Burst: 100A for 10 seconds *Keep in mind that the size of the wire and type of wire insulation is the main limiting factor. More heat is generated in smaller wires and in poor connections. We have tested the switch with 10ga wire and were able to run 95A for 3 minutes.
