Typical Switch Life
Sure Grip Handles use reliable snap action micro switches that have proven to give the longest life and greatest reliability of any switch on the market.

While the switches are rated for up to 10 million cycles, switch life is dependent on several factors that can greatly influence the number of on/off cycles that a switch can perform before it fails. The load (in amps) and proper diode protection are two of the greatest factors that will determine the life of a switch.

The graph below shows the typical life of our switches, comparing load in amps to the number of on/off cycles that can typically be expected.

The switching capacity of the switch depends on the type of load that the switch is switching and the contact material. Sure Grip Handles use switches with silver plating on the contacts for maximum load capacity and long life. If the handles will be switching logic level signals (under 20 mA), the best performance will be obtained using switches with gold plated contacts.
