Notes:
1. Switches may be mounted in any direction. Some are more sensitive than others.
2. This switch is designed to be used in a high impedence circuit to detect change of state. Closed contact resistance will typically be below 1ohm at 1 milliamp.
3. Patented under one or more of the following numbers: US patent 5.354.958
