Swichgage instruments are high-quality diaphragm-actuated, dial gauges for various with built-in electrical switches.
Used for tripping alarms and/or shutdown devices, the pointer acts as both an indicator and as one switch pole which completes a circuit when it touches the adjustable limit contact.
Contacts have a self-cleaning motion to ensure electrical continuity.
More compact, gauge-only models without contacts (known as Murphygage instruments) are also available.
