The application of vibrations or shocks in excess of the spring limit may cause resonance of the spring which results in a loss of contact stability and intermittent contact. ●The construction does not prevent the effects of humidity, pressure, or the atmosphere (i.e., gases, oils, and liquids). (Gases, depending on type, may penetrate the spring material inside. The penetration of gases, oils, or liquids that form a film on the contacts may causes changes of the insulation or may cause the contacts to cease to conduct.) ●This product is not magnetically shielded and as such the attention must be paid to the following points. (1) The plate used to mount this product should be made of non-magnetic material. (Aluminum plate is preferable.) (2) Avoid the use of magnetic material and anything that may produce a magnetic field such as a magnet in the proximity of the switches (roughly a 15 mm square). 140 ■External Dimensions 110 HCS2-----120-----F 130 140 150 111 HCS2-----121-----F 131 ■Circuit Diagram ■Typical Data When Switching Signal is OFF Switching signal Auxiliary contacts Coaxial connectors 111 HCS2-----121-----F 131 Switching signal Coaxial connectors 110 HCS2-----120-----F 130 140 150 141
