Grips / Solenoids Switches Relays (Guardian)

Our standard solenoids and switches in various voltages can be modified to fit your application, or we can custom design a precision solution to meet your requirements. Relays are ready-to-use or custom engineered in a variety of amps in sealed or non-sealed configurations.

Serving the commercial and defense aviation communities since the mid 1940s, we are established as a leader in aerospace control grips. We have the expertise to produce grips and relays to accommodate your aerospace control requirements and withstand the rigors of flight.

We manufacture a standard line of solenoids, including AC and DC frame solenoidsDC latching solenoids, and laminated solenoids produced in various standard voltages. For custom applications, our standard solenoids can be modified to fit a particular application or we can design a new solenoid to meet a specific requirement. All catalog solenoids are UL Recognized and RoHS compliant (2011/65/EU). We offer solenoids in push or pull types and also magnetic latching designs. We can create application-specific solenoid designs with:

• Custom actuators
• Spring returns
• Custom mounting
• Custom terminations

In addition, we offer a full line of spring kits which are perfect for application development and prototype designs. Multiple springs with a range of spring forces are included and are color coded for easy recognition. Kits for pull type solenoids include a plunger/actuator, and all kits include necessary hardware.

All of our solenoids are:
• 100% Made in the USA
• UL recognized components
• RoHS II Compliant
• ISO9100:2009 Certified
