GLH3 Product Introduce

Model


GLH1 No Load Switching 
Low, stable contact resistance minimizes loss in RF circuits 
High carry current, 25Adc continuous, in a small package 

GLH3 Make & Break Load Switching 
Durable tungsten contacts for hot load switching 
Vacuum dielectric for effective arc quenching when opening under load 

GLH5 Make Only Load Switching 
Excellent for capacitive discharge and safety dump switch applications 
Additional isolation capabilities in many applications (consult factory) 
Consult factory for load switching applications
