Has your robot been lacking a high-current power switch? Tired of plugging and unplugging the battery during an intense competition? The Mini Switch can be activated with the simple twist of an allen key. No other switch is as small, lightweight and powerful!
Specs
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.
Operation
To connect the two copper terminals, use a 3/32" hex wrench to tighten the screw (clockwise).
Note: 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.
Allowable soldering temperatures
350C: continuous
400C: 1min
450C: 12s
480C: 8s
Current Ratings (using 16-gauge wire)
Rated Current: 40A
Burst: 100A for 10 seconds
Note: 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. This switch has been tested with 10ga wire and is able to run 95A for 3 minutes.
