Siemens 52PP2A2A Heavy Duty Mushroom Push-Pull Button Unit, Water and Oil Tight, 2 Positions, Maintained Operation, 1-3/4" Head, Metal, Red, 1NO - 1NC Contact Type

This Siemens 52PP2A2A pushbutton unit has a red metal pushbutton actuator and an assembled contact block, and is suitable for use in wet or oily environments. The 1-3/4" diameter mushroom-shaped pushbutton actuates a normally open (NO) contact and a normally closed (NC) contact using pull-to-start and push-to-stop operation for maintained on/off operation. The contact block is rated at up to 600V and up to 7,200W power input. The pushbutton unit has a 30 mm diameter shaft and is intended to mount in a Siemens enclosure (not included). This pushbutton unit is Underwriters Laboratories (UL) Listed and Canadian Standards Association (CSA) certified for quality assurance and is suitable for use in an application such as controlling an electrical circuit in a manufacturing process control system.SpecificationsPushbutton type1-3/4" metal head, mushroom-shaped pushbutton and assembled contact block, redOperation typePush and pull, two-position maintained contactPower inputUp to 600V, up to 7,200W power inputContact type1 NO + 1 NCSpecifications metUL Listed, CSA certifiedPushbutton switches make or break electrical connections as part of a system that controls a process, such as a manufacturing line. Indicator lights with labels or color-coded caps are used to display the current state of a process, such as "completed." The pushbutton unit is composed of a pushbutton actuator for making or breaking electrical connections, a holder for securing the actuator to a control panel and for housing a light, and one or more contact blocks for connection to electrical wiring. Contacts within a contact block can be normally open (NO) or normally closed (NC), so that pressing the button starts or stops a process. Holders accommodate a range of control panel thicknesses and may include lamps to illuminate the button. Pushbutton actuator head types include mushroom, flat-surface, raised-surface, and key-operated, and may be illuminated, color-coded, and labeled. According to the requirements of an application, actuators may operate only as long as the button is held or they may lock into position when pushed and unlock when pulled or twisted. Pushbuttons and indicator lights are used in applications such as manufacturing process controls and as emergency shutoffs in industrial workplaces.Siemens manufactures electronic products for building automation, industrial drives, lighting, energy generation, medical equipment, and rail transportation. The company, founded in 1847 and headquartered in Munich, Germany, meets International Standards Organization (ISO) standards 14001, 9001 and TS 16949.
