Zusammenfassung:PURPOSE:To reduce the number of contacts so as to reduce cost, and to inhibit the generation of such as the welding of the contacts by forming a mechanism having contact for series, out of a single-brake contact that has a moving contact arm, the end of which is fixed. CONSTITUTION:A hybrid relay is formed out of a mechanism 12 which has contacts for input and is placed in an input signal circuit X and a mechanism 1 which has contacts for output at larger intervals than the mechanism 12 and is placed on an output mechanism Y, and a mechanism 5 which has contacts for series at smaller intervals than the mechanism 12 and is placed in the input signal circuit X. A mechanism Y having contact for output is formed out of double-brake series contact, while the mechanism 5 having contact for series is formed out of single-brake contact that has a moving contact arm, which is fixed in the end, and each contact mechanism is formed in such a way that it is switched and operated by electromagnets which differ from each other among them. The number of contacts is reduced, and cost is cut, while the generation of the chattering of the mechanism having contact for series is eliminated, and the generation of unexpected accident such as the welding at the time of leading large current, is thus inhibited.
