Delayed action contact blocks have a time delay before they switch state after the button or switch is pressed.
What is the insulation resistance of the contact blocks?
The insulation resistance of these contact blocks is greater than 10 Mohm.
Can these contact blocks be used in conjunction with other types of control devices?
Yes, these contact blocks can be used with timers, relays and sensors.
