You may have come across terms such as SPST, SPDT, DPST, and DPDT in product specifications, wiring diagrams, or electrical catalogs. But what do they actually mean, and which configuration is right for your application? These abbreviations describe the number of poles and throws in a switch. In simple terms, they tell you how many separate circuits a switch can control and how many connection paths are available to each circuit. Choosing the wrong configuration can lead to unnecessary wiring complexity, limited functionality, or [&hellip;]<\/p>\n","protected":false},"author":3,"featured_media":4553,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_uag_custom_page_level_css":"","footnotes":""},"categories":[1],"tags":[],"class_list":["post-4552","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"uagb_featured_image_src":{"full":["https:\/\/onpowbutton.com\/wp-content\/uploads\/2026\/11\/types.webp",454,398,false],"thumbnail":["https:\/\/onpowbutton.com\/wp-content\/uploads\/2026\/11\/types-150x150.webp",150,150,true],"medium":["https:\/\/onpowbutton.com\/wp-content\/uploads\/2026\/11\/types-300x263.webp",300,263,true],"medium_large":["https:\/\/onpowbutton.com\/wp-content\/uploads\/2026\/11\/types.webp",454,398,false],"large":["https:\/\/onpowbutton.com\/wp-content\/uploads\/2026\/11\/types.webp",454,398,false],"1536x1536":["https:\/\/onpowbutton.com\/wp-content\/uploads\/2026\/11\/types.webp",454,398,false],"2048x2048":["https:\/\/onpowbutton.com\/wp-content\/uploads\/2026\/11\/types.webp",454,398,false],"trp-custom-language-flag":["https:\/\/onpowbutton.com\/wp-content\/uploads\/2026\/11\/types-14x12.webp",14,12,true]},"uagb_author_info":{"display_name":"hongbo","author_link":"https:\/\/onpowbutton.com\/ja\/author\/hongbo\/"},"uagb_comment_info":0,"uagb_excerpt":"When choosing an electrical switch, one of the first things to consider is how many circuits it needs to control and how those circuits should operate.
