Temperature switches

Configurable ALERT thresholds for autonomous temperature protection

We offer the largest selection of configurable temperature switches that reduce your production cost with their self-test feature and enable systems to be protected autonomously with integrated, selectable hysteresis for enhanced noise immunity. The threshold temperature at which our switches trigger an alert can be resistor programmable, pin-selectable or factory set.
