ALPS Introduces the SDDJF1A Series Slim Type One Pole Rocker Power Switch

With conventional power switches generally adopted in flat-screen TVs, minute electrical current flows to the TV set even in Off status and thus the set consumes standby current. However, AC power switches directly switch the power line On/Off, with zero standby current when the switch is Off, as if the TV set power plug was disconnected. Adoption of AC power switches for flat-screen TVs is under review due to growing environmental and energy saving awareness as well as European energy saving regulations*2.

This switch achieves a thickness of 5.2mm which is approximately 1/3 of ALPS' conventional switch (SDDJE Series, thickness 12.4mm). The switch's contact structure features ALPS' original torsion spring to create a secure contact point, and maintains a stable load in the contact point which increases contact reliability. Its wiping structure, where the traveling contact wipes the fixed contact point, further improves contact reliability.

As power switches turn On/Off in high voltage of AC100V – AC240V, secure insulation properties are required. Normally it is difficult to ensure insulation for a small, thin switch that is installed within a compact space on the application product. However, ALPS has adopted an original internal structure (patent pending) for the SDDJF1A Series that prevents degradation of insulation properties, and secures a high level of insulation in a low-profile body.

This product supports solder mounting and “one-touch connectors (Faston #187).

*2 A typical European energy efficiency regulation would be the ErP Directive, which requires environmentally considerate design in energy-using products to encourage energy saving design in electrical/electronic products.
