Review on MTS 101 Position Miniature Toggle Switch by Carlos Barete

When they're good, they're good, but. Common problems: 1) Physically stuck in one position (does not move) 2) High on-resistance (greater than 1 ohm) 3) Plastic housing melts easily (causing complete switch failure) The pre-use test solves the following problems: test mechanical and ohmmeters before use. Even with this failure rate, the beginner's test and the fast soldering, the price/performance ratio is right. All these problems are solved by buying from Mouser, Digikey, etc. for 3-4 times more expensive.
