Relay

A relay comprising:

• a. an electrically insulating means having a planar partition defining a first and a second side of said insulating means;
• b. at least one contact unit fixed to each of the first and second sides, each contact unit having at least two contact members with each member having two ends wherein the first end is a contact end and a second end, opposite said first end, is connected to an elongated plug connector for enabling said relay to be plugged in, at least one of said contact members being an elongated contact spring fixed to the insulating means on said second end wherein a longitudinal axis of said contact spring is substantially parallel to the plane of the partition, the contact end of the contact spring being movable parallel to the plane of the partition and movable perpendicular to the longitudinal axis of the contact spring;
• c. an actuating member for facilitating movement of the contact end of the contact spring, said movement resulting in making or breaking a contact between the contact ends of the contact members;
• and
• d. a plurality of plug connectors, wherein a first portion of said plurality of plug connectors is provided for plugging in the relay and is arranged on the first side proximal to the second end of the contact spring, a longitudinal axis of said first portion of plug connectors being arranged perpendicular relative to the planar partition in order for said first portion of plug connectors to be plugged in a perpendicular direction with respect to the planar partition;
• and a remaining portion of the plug connectors is located on the second side offset a first predetermined distance from the first portion of plug connectors in a direction towards the first end of the contact spring, and is connected to contact members located on the second side by connecting elements which bridge the first predetermined distance, said second portion being arranged at a second predetermined distance from the contact spring in a direction parallel to the plane of the partition, and a being arranged perpendicular to the longitudinal axis of the contact spring to provide a free movement of the contact spring when the contact end of the contact spring is moved by the actuating member.
