Series A7 Mini Pressure Switch

Designed for OEM’s, High Current Capacity

Series A7 Mini Pressure Switches have been designed for high current applications. These switches are small and inexpensive, making them ideal for OEM use. The Series A7 switches utilize a high-quality snap-action switch, which is diaphragm actuated. They have a silicone diaphragm and nylon housing. The A7 switches are compact and lightweight which adds to the ease of installation. The set point must be factory set, but a broad operating range makes them great for a variety of applications.

  • Models are built to your specification.
  • Set point is factory preset and is not field adjustable.
  • Minimum quantity order is 100.

Questions

Question
For which pressure switch applications are gold contacts recommended?
Answer
For "dry circuit" applications where little or no current is flowing in the circuit to help burn off contact dirt and oxidation. Switches used with solid state circuits often fall in this category.
